Directed Interpolation and Data Post-Processing

Abstract

An encoding device evaluates a plurality of processing and / or post-processing algorithms and / or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods / algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm / method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm / method at the decoder / post-processor and / or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and / or error correction techniques that contribute to a restoration of the downsampled images.

AI Technical Summary

Problems solved by technology

The present inventors have realized that current methods for reconstruction of downscaled or otherwise compromised video and other data can be severely limited in performance, or constrained in terms of complexity, given that the conversion process has little or no information about the original nature and characteristics of the content.
